Hollow cathode lamp-excited ICP atomic fluorescence spectrometry—an update

Signal enhancement of elements due to the presence of carbon-containing compounds in inductively coupled plasma mass spectrometry

“…However, the addition of propane significantly enhanced the fluorescence signal of Ca and Mo. Demers (8) used the same torch configuration and found that a moderate addition of propane (10 mL min'1) reduced the formation of oxides with a dissociation energy between 4 and 6 eV. A larger concentration of propane (50 mL min'1) was needed for the dissociation of oxides with an energy greater than 6 eV.…”

“…0003-2700/91/0363-1497J02.50/0 DISCUSSION Additions of methane and propane have already been used in ICP atomic emission spectrometry (AES) (5,6) and atomic fluorescence spectrometry (AFS) (7,8). The purpose of the addition of these gases was to reduce the formation of the refractory oxide by producing CO, with the following proposed reaction: MO + C -M + CO Alder and Mermet (5) used a 6-kW ICP.…”

Determination of phosphorus by molecular absorption of phosphorus monoxide using a high-resolution continuum source absorption spectrometer and an air–acetylene flame

“…There is considerable literature dealing with the determination of phosphorus. Analytical techniques range from the classic gravimetric, 2 volumetric, 3 and spectrophotometric approaches [4][5][6] to modern instrumental methods such as nuclear magnetic resonance (NMR), 7 mass spectrometry (MS), [8][9][10][11] neutron activation analysis (NAA), 12,13 polarography, 14 amperometry, 15 ion chromatography, 16 X-ray fluorescence spectrometry, [17][18][19] atomic fluorescence spectrometry (AFS), 20 atomic absorption spectrometry (AAS), [21][22][23][24][25][26][27][28] and optical emission spectrometry (OES). [29][30][31][32] Phosphorus is one of the few elements still determined extensively by spectrophotometric methods, which are usually based on the formation of yellow phosphomolybdic 5 and vanadophosphomolybdic acids 4 or on their reduction products called ''molybdenum blue''.…”

Atomiser, source, inductively coupled plasmas in atomic fluorescence spectrometry (ASIA): a study of chemical and ionisation interference effects

“…In these arrangements the ICP has been used as a source with the flame as an atomiser [1][2][3][4][5], as an atomiser with other devices as a source [6][7][8][9][10][11][12][13][14][15][16][17][18][19] and as both source and atomiser in the same system [20][21][22][23][24][25][26][27][28].…”
